[Elecraft] MH2: microphone

[Paul at N4LCD.com]

>They are virtually identical. Same basic mic element, case etc.

>We took over manufacturing this when Heil discontinued his OEM 
>version suddenly. Apparently he had purchased a group of excess mics 
>and had replaced the dynamic element with the Electret element. 
>(Leaving the unused dynamic element unused inside the case.) When he 
>ran out he suddenly stopped selling them, so we had to locate the 
>manufacturer of the plastic cases and spec our own custom version.

>For our MH2, the only changes were to eliminate the unused  dynamic 
>element left inside the case by Heil, and to improve the foam 
>mounting for the electret element for better mechanical support. 
>Overall the two mics sound identical. We've bought a very large 
>quantity of these and they will be around for some time. :-)

Is the old Elecraft/Heil MD2 plug and play with the K3?
